ENVELOPMAGHINE.

Specification of Letters Patent.

Patented Dec. 15, 1914.

To all whom it may concern Be it known that I, ABRAHAM Nevron, a citizen of the United States, and a resident of New `i'ork, borough of Brooklyn, in the county of iiings and State of New York, have invented certain new and useful Improvements in lunvelop-lwlaclnnes, of which the following is a specification.

This invention relates to envelop machines, and particularly to that class there-A of which is adapted for manufacturing at high speed large open ended envelops, commonly known as catalogue envelops.

The object of my improvements is to pro vide a machine of the class specified, adapted to be operated with accuracy and precision at high speed, and adjustable for producing a variety of lsizes of envelops of different widths and diiferent lengths.

ln the drawings accompanying this specification, l have illustrated the preferred embodiment of my improvements, where Figure lis a side elevation with the front frame removed of the blank feeding portion of my improved machine. Fig. 2 is a continuation of Fig. l, illustrating the side flap folding mechanism. Fig. 3 is a continuation of Fig. 2, illustrating the end flap folding and gumming mechanisms. Fig. 4 is a plan viewcorresponding with Fig. 1. Fig. 5 is a plan view corresponding with Fig. 2. Fig. 6 is a plan view corresponding with Fig. 3, and Fig. 7 is an end elevation looking into the machine from the right hand side of Fig. 3.

The several figures of the drawings are to a uniform scale.

Before describing the invention in detail l desire to have it understood that the invention is not limited to struction and arrangement of parts which I have illustrated and shall hereinafter describe, and that various changes may bf made in the mechanisms shown without departing from the spirit or scope of the invention, and that the phraseology which i employ is for the purpose of description and not of limitation.

The present invention comprises means for forming from a suitably shaped blank a completed envelop, having one side flap folded over and gummed onto the other side flap, the bottom flap folded over and the particular con f gummed onto said side flaps, and having the seal flap gummed and the gum dried thereon ready to be folded over and moistened for sealing the envelop. The general character of the blankwhich this machine is particularly adapted to make into an envelop is of general rectangular form having corner portions cut therefrom, as shown at 5 in Fig. 4.

My improved machine comprises means for supporting a pile of such blanks, for re-. moving the topmost blank from the pile and delivering it to primary advancing means. Coacting with said primary advancing means are means for retarding the blank into synchronism with subsequent advancing means, and said retarding means is also eliicient for positioning the blank widthwise of the machine. After the blank has been thus synchronized and positioned, it is delivered into the control of intermediate advancing means, which delivers it into engagement with side iap gumming means and lengthwise creasing means for forming two lengthwise creases on which the side flaps will presently be folded. The blank is then advanced into the control of secondary advancing means. Oppositely disposed relatively to said secondary advancing means are means for turning upwardly and then folding inwardly and downwardly successively, onto the body of the blank, the side flaps thereof. T hat side flap which is folded down first, having been previously gummed upon its bottom face, which in its folded position is its upper face, receives the other side flap on its gummed surface. For coaction with the side flap folding means, I provide means for holding the body of the blank in engagement with the secondary adw vancing means, and after the side flaps are folded I provide means for holding the one side flap against the other thereof, during further advancement of the partly folded blank. Said partly folded blank is then delivered onto a third advancing means, and while thereon means operate to retard its advancement, and other means operate to position it widthwise of the machine. Means for creasing the seal flap and means for creasing the bottom flap then perform their functions, preferably simultaneously, upon the blank, and gumming means supplies gum to the body of the blank for sealing the bottom flap thereonto. Bottom flap folding means and bottom `ap 'ironing means thereupon successively operate to fold and squeeze down the bottom flap onto the envelop body. The now nearly completed envelop, with its finished bottoni,- leading, is then delivered to a fourth advancing means, operable for advancing the ehvielops with their seal flaps in overlapping succession. Seal flap gumming mechanism is provided for applying a continuous web of gum to said overlapping seal Haps, as they are advanced by said fourth advancing means, and said envelops are then delivered into the control of a fifth advancing means. Drying means for said gummed seal flaps comprises Y a blast of air directed against said seal flaps 'the provided adjustments being operated in( While they are being advanced by said fifth advancing means, and by which fifth advancing means the completed envelops are delivered from the machine, just below the position in which the blanks are first introduced into the machine.

The present application includes submechanisms whichform the subject .matter of my co-pending applications, Serial Number 763,250, filed April 24, 1913, and Serial Number 781,090, filed July 25, 1913, and herein l have illustrated those suhmechanisms in their relations to a complete envelop machine.

Within predetermined limits several of the submechanisms of my improved machine are adjustable widthwise, and others thereof are adjustable both widthwise and lengthwise, whereby the machine is adapted for producing envelope of different widths and lengths, and having dilferent lengths of bot-- tom and seal flaps. Furthermore, to facilitate the change from one size of envelop to another, said adjusting means are so interconnected as to permit a certain plurality of unison, and further means are provided for operating in unison other pluralities of adjusting means. Through these provisions a minimum vof skill and time is required. for setting up the machine to produce any given envelop within its scope. l

In describing in detail the several features f of my improved machine, I will first direct attention to the means for successively advancing the blank through the machine, and

the means provided for adjusting those ad-l vancing means crosswise of the machine.V-

At the left hand end of Figs. 1 and 4,

table 2, having adjustable side guides 3 and 4, is provided for supporting a stack comprising a plurality of envelop blanks such as 5, arranged in staggered relation, with the uppermost blank in position to be separated from the stack by means of delivery rolls 6 and 7. Said delivery rolls are each provided with a rubber foot, as 8 to roll 6, for engaging the leading end of the leading blank and delivering that blank to the primary advancing means. Said separating and delivery rolls 6 and 7 are adjustably thereof under rolls 6 and 7 on pulleys 14 and 15 on shaft 1G. For simplicity of construction and adjustment, l preferably fiX pulley 15 permanently to said shaft 16, and adjust pulley 14C toward and from said pulley 15 to accommodate dierent Widths of blanks. This arrangement of one xed pulu ley and one adjustable pulley is adhered to throughout the other advancing means hereinafter described. The other ends of said belts 12 and 13^are supported on pulleys 18 and 19 respectively on shaft 17; pulley 19v being fixed thereto and pulley 18 being adjustable lengthwise said shaft. Pulleys 11i and 18 are slidable on keys as 20 iixed in their respective shafts. Said pulleys may be adjusted in unison toward and from their movement, but held against longitudinal 9 movement. Said shaft 21 is provided with a threaded portion 22, having a nut 23 in engagement therewith. Said nut 23 is pro-v vided with oppositely extending arms 24 and 25, each terminating in bifurcated ends which engage suitable grooves in the hubs of pulleys 14 and 18 respectively. Thus, by rotating shaft 21 by means of its squared end, pulleys 14 and 18 may be caused to move toward and from their complementary pulleys equal amounts and at the sa-me time. For coaction with belts 12 and 13 directly' over pulleys 14 and 15 respectively, I provide rolls as 26 conveniently hung on arms as 27, for retaining the successive blanks on said belts. Said arms asv 27 may be conveniently pivoted in brackets as 28, andsaid brackets may be adjusted crosswise of the machine on rod 29 and secured in any desired position by means of the usual set screws. F or supporting the upper runs of belts 12 and 13 respectively,` l provide table 30 fixed to cross rods as 31 supported in side frames 10 and 11. I l

The secondary means which I have provided for advancing the blank comprises another pair of endless belts 32 and 33, mounted and adjusted similarly to belts 12 and 13 already described. The rearward end of belts 32 and 33 arey supported on pulleys 34 on shaft 35, and the forward end of said belts are supported on pulleys as 36 on shaft 37. Pulleys 34 and 36 are slidable crosswise of the machine on theirrespective shafts, and pulley 36 is constrained to j Said shafts are provided with threaded portions 42 and 43 for engagement with nuts 44 and 45 respectively, having upstanding arms fixed to adjacent portions of said bar 39. When one of said shafts 40 or 41 is rotated the other shaft is caused to rotate therewith by means of sprocket and chain connections to be hereinafter described.

Located above feed belts 32 and 33 I provide co-actingbelts 46 and 47, traveling in unison therewith for holding the blanks against said belts 32 and 33 respectively. Said belts are endless and are supported at their rearward ends on pulleys 48 and 49 respectively on shaft'50. Pulley 49 is preferably fixed to said shaft and pulley 48 is slidably mountedAthereon and constrained against rotary movement by key 51. Belt 46 on the near side of the machine as viewed in the drawings is considerably shorter than its companion belt 47. This relative difference is to provide room beyond the end of said belt for turning over the near side flap before the turning over of the far side flap, as more fully explained hereinafter. The forward end of said belt 46 is supported on small pulley 52 turning freely on stud 53 fixed in one of the arms of carrier 54. Another arm of said carrier 54 reaches rearwardly and is bifureated for engagement with the grooved hub of pulley 48. Said carrier 54 is mounted for traverse crosswise of the machine on bracket 55 supported on upstanding portions of side frames 10 and 11. Said carrier 54, the arms of which control the position of belt 46 crosswise of the machine, may be moved back and forth on bracket 55 by means of sha-ft 56, having a threaded portion 282 in engagement with a nut portion of carrier 54.

.Said shaft 56 is constrained to rotate in unison with other cross-adjusting shafts by means of gearing to be more fully described hereinafter. The forward end of belt 47 is supported on pulley 57 turning freely on stud 58 fixed in arm 59 forwardly reaching from bracket 55. It will be observed that said belts 46 and 47 are provided for coaction with the earlier portions of feed belts 32 and 33; for coaction with the later portions of those feed belts respectively, I provide another pair of belts 60 and 61. In this case near belt 60 is the lon er and far belt 61 is the shorter, thus supp ementing the opposite, relative positions of belts machine toward 46 and 47. Belt 60 at its front end is supported on'small pulley 62 turning freely on stud 63 in bracket 64 fixed to adjusting bar 39. The forward end of saidA belt 60 is supported on and driven by pulley 65, slidably mounted on shaft 66 and `constrained to rotate therewith by key 67.

Upstanding from adjusting bar 39 is plate 68, having its bifurcated upper end in engagement with the groove in the hub of pulley 65. It will thus be seen that both ends of belt 60 are controlled in adjustment crosswise of the machine by bar 39. The rearward end of belt 61 is supported on small pulley 69 turning freely on a stud in arm 70 upstanding from sleeve 71 inreaching from side frame 11 and surrounding shaft 41. The forward end of said belt 61 is supported by and driven from pulley 72 fixed to said shaft 66. Another arm 73 is fixed to sleeve 71 and carries a small pulley for supporting the upper run of feed belt 33 just under the point of folding over the' far side flap. It will be observed that between the delivery end of feed belts 12 and 13 and the receiving end of feed belts 32 and 33 is an open space. This space is partly occupied by a pair of small rolls 75 and 76 for assisting the blank from the first mentioned pair of belts to the second mentioned pair. Said rolls are pivoted in side frames 10 and 11 and are of such extent crosswise of the machine as to coact for advancing, any width of blank which the ma chine is capable of operating upon.

For holding the blank against the secondary advancing means during the folding of the side flaps, I provide other means, comprising a plurality of rolls located above each of feed belts 32 and 33 for coaction therewith. Said rolls, as 77 over belt 3,3, may be arranged to be urged by gravity to coaction with said belt, or springs as 78 may be employed to increase their efficiency. Said rolls as 77, maybe supported and guided in outreaching portion 79 of arm 59, and those rolls for engagement with belt32 may be supported and guided in arm 80 outreaching from carrier 54.

' Subsequent to the secondary advancing means, I provide a third advancing means, comprising another pair of endless belts 81 and 82. In conformity with the 'previous sets of feed belts, I preferably provide belt 81 with adjusting means erosswise of the and from belt 82 and in parallelism therewith, and mount the carrying means for belt 82 in fixed relation crosswise of the machine. The driving pulleys for said belts 81 and 82 are fixedto shaft 83, having bearings in side frames 10 and 11, the driving pulley 84 for belt 81 being mounted for movement crosswise of the machine on said shaft and constrained to rotation with that shaft by key`85, -For on said shafts.

moving said pulley 84 lengthwise shaft 83 when desired, the forward end of bar 89 engages a groove in the hub of said pulley. By this means belt 81 is adjusted in unison with belt 32. -Said belts 81 and 82 are further supported on pulleys such as 86 on shaft 87 and pulley 88 on shaft 89. Said shafts `87 and 89are supported in auxiliary side frames 100 and 110 and are held against rotation therein, said pulleys rotating freely F or adjusting pulley 86 crosswise of the machine, l provide shaft 91 mounted for rotation in side frames 10 and 11, and threaded at 92 for engagement with an internally threaded hub of bifurcated arm 93, in engagement with a groove in the hub of said pulley 86.` For edecting said cross-adjustment inunison with the crossadjustment of pulley 84, shaft 91 and the adjusting shafts for bar 89 are geared together, as more fully described hereinafter. Other supporting means for belts 81 and 82, and which means are adjustable lengthwise of the machine, include pulleys such as 94, 95 and 96, mounted for free rotation on shafts fixed in carriage 97. Said carriage is mounted on suitable ways on side frames 100 and 110 for adjustment lengthwise of the machine, and said carriage isprovided with rack and gear means for effecting such adjustment.

A fourth advancing means comprises a pair of endless belts 98 and 99 supported on pulleys, as 101 and 102 for belt 98. Upper pulley 101 and its companion pulley for belt 99, are .mounted for free rotation on shaft 108 fixed inyoke arms 104 and 105. Said pulleys on shaft 108 may be constrained to their desired positions on said shaft by the usual collars, those for pulley 101 having set screws therein. Lower pulley 102 and its companion pulley for belt 99 are fixed to shaft 106, said pulley 102 being adjustably fixed thereto. Shaft 106 has fixed thereto gear 107 for engagement with large gear 108 on drier drum shaft 109, whereby the drier' drum and belts 98 and 99 will be actuated at the'same surface speed. For coaction with belts 98 and 99 there is another pair of belts, one of which 111, for coaction with belt 98, is clearly shown in Fig. 8. -Said belts as 111 are also endless and are supported on pulleys as 112 adjustably fixed to shaft 113, and

loose pulleys as 114 mounted on a shaft in side frames 100 and 110, and pulleys as 115 mounted on a shaft in brackets as 116 adjustably mounted for movement up and down on yoke arms 104 and 105.

from drier drum gear 108 through intermev diate gear 118. Belts 98 and 111 and their Shaft 113 has gear 117 fixed thereto and is driven varound pulleys and 128 respectively mounted for free rotation on shaft 124: fixed in side frames 100 and 110. Said pulleys may be constrained against endwise movement on said shaft by the usual collars, and the collars for pulley 122 may be held in adjusted positions endwise said shaft by means of the usual set screws. Directly below shaft 109, the lower runs of belts 119 and 121 are further supported by pulleys 125 and 126 respectively, mounted on shaft 127 similarly to the mounting of pulleys 122 and 123 on shaft 124. Said belts 119 and 121 extend rearwardly and slightly upwardly under the machine to approximately below the position in which the envelop blanks' are originally delivered to the machine. The long reach of said belts and their slow movement provide time for the drying of the gum `on the seal flaps. Said belts 119 and 121 are supported and driven at their delivery end by suitable pulleys as 128, fixed to shaft 129 revolubly mounted in side frames 10 and 11.

tively of said belts, are belts as 131 for retaining the envelops on belts 119 and 121. Said belts as 131 are supported adjacent drum 120 on pulleys as 182 mounted for free rotation on shaft 183 fixed in side frames 100 and 110, andthe other ends of said belts are supported on and driven by pulleys, as 134 on shaft 185, just over shaft 129 in side frames 10 and 11. One of said pulleys 184 is mounted for endwise movement on said shaft 185 and is constrained to rotation therewith by key 136. For adjusting belt 131 crosswise of the machine toward and from its companion belt, I shift pulley. 132 by means of threaded shaft 137, rotatably mounted in side frames 10 and 11. Said shaft is inthreaded engagement with arm 188 whose bifurcated end engages a groove in the hub of said pulley 132. The delivery ends of belts 119 and 121, and of belt 181 and its companion belt, are adjustable crosswise of the machine by means of arm 139, whose bifurcated end engages grooves in the hubs of pulleys 128 and 134 respectively. Said arm 139 is in threaded engagement with shaft 14() having bearings in side frames 10 and 11. Said threaded shafts 137 and 140 are caused to rotate in unison, when either thereof is turned by means hereinafter described. It will be observed that after any kcrossadjustment of pulley 128 carrying the delivery end of belt 119, has been made, pulleys 122 and 125 must be shifted by hand to restore belt 119 into parallelismwith belt 121. For driving shafts 129 and 135 for actuating the belts now being considered, I gear those shafts together by gears 143 and 144 respectively, and fix to shaft 129 sprocket 145 driven by chain 146 from sprocket 147 fixed to shaft 148, and which shaft has also fixed thereto gear 149 for engagement with gear 108 of the drier drum shaft.

For turning over the side flaps of the blank, as 150 and 151, of blank 5, Fig. 4, I employ a plurality of opposite turning blades or fingers as 152 and 153 for side flap 150, and 154 and 155 for side flap 151. The turning fingers for the rear side-Hap as 151 are supported from bar 156, fixed to brackets 157 and 158 inreaching from side frame 11. The turning fingers for the front side fiap as 150 are supported from adjustable bar 159. Said fingers for both the front and rear flaps are universally adjustable relan tively to their supporting `bars respectively, as well known in the art. Bar 159 is carried by downwardly reaching ears 160 and 161 in threaded engagement with adjusting shafts A162 and 163 respectively, whereby when those shafts are rotated in unison, bar 159 will be movedtoward or from bar 156, as the case may be, and in parallelisnr` therewith.

For causing the several crosswise adjusting shafts to rotate in unison'for adjusting crosswise of the machine the several feed belts, with which they are connected, I interconnect those threaded adjusting shafts as 21, 140, 40, 56, etc., by means of gearing; in some places employing chain and sprocket gearing, and in some places intermeshed toothed gearing. For instance, shaft 21 has fixed to the rear end thereof sprocket 164 Aconnected by chain 165 with sprocket 166 fixed to shaft 40. Shaft 140 has sprocket 167 fixed thereto connected by chain 168 with sprocket 169 on shaft 137. Shaft 56 is connected by means of gear'171 fixed thereto, to shaft 40 by means of gear 172 fixed thereto, through intermediate gear 173. Shaft 40 has sprocket 174 fixed thereto connected by chain 175 to sprocket 176 fixed to shaft 41.

182 on shaft 91. For connecting adjusting shafts 21 and 140 I fix to the former thereof gear 278, and to the latter thereof gear 279 connected by intermediategear 280. It will Sprocket 180 also fixed to shaft 41 is connected by chain 181 with sprocket thus be seen that the cross-adjusting means for the first, second, third and fifth advancing means are so interconnected, that the rotation of one of their threaded adjusting -shaft will cause an equal rotation of all the others of those shafts, whereby said advancing means will be adjusted in unison. For rotating in unison adjusting shafts 162 and 163 of bar 159, carrying one set of side folding fingers, I provide shaft 162 with sprocket and for simultaneously locating the blank,

crosswise of the machine. Said means com'- prises a pair of pins, one of which is clearly shown at 183 in Fig. 1. Said pins engage the envelop blank in the rentrant corners of its leading end, and retard the blank relatively to feed belts 12 and 13. Said belts urge the blank against said pins, whereby said blank is located crosswise of the machine and retarded into synchronism with the succeeding advancing means. Said pins as 183 are fixed to planetary shaft 184, and which shaft is mounted and actuated for rotation in a circular orbit about shaft 185, having bearings in side frames 1() and 11. To shaft 184 is fixed gear 186, connected through intermediate gear 187 with gear 188, normally fixed coaxially with shaft 185. The relative sizes of gears 186 and 188 are such as to cause pins as 183 to maintain a vertical position respectively, relatively to the path of the envelop blank. For oscillating said ins as 183 forwardly in their d1- rection of) travel, after they have performed their function of synchronizing the blank, and so as to promptly withdraw them from the path of the blank, I provide means .for oscillating gear 188. Said means comprises segment gear arm 189, in mesh with gear 188 andfixed to shaft 190, rotatably mounted in side frame 11. For rocking said arm and shaft, I provide arm 191 having a roll pivotally mounted in its free end for engagement with cam 192 fixed to shaft 1 85. For convenience of construction I rovide two sets of pins as 183 diametra ly are ranged relatively to shaft 185. Said pins as 183 are mounted for crosswise adjustment on their respective shafts'as 184,l to accommodate different widths of blanks. After the blank has been synchronized and positioned crosswise of the machine by the means just described, it is delivered between feed rolls and 76, and advanced by those rolls to en agement with upper and lower creasing ro ls as 193 and 194 respectively. Upper creasing rolls 193 and 195 are fixed to shaft 196, `and the lower creasing rolls, as 194, are fixed to shaft 197. Creasmg rolls .193 and 194 are adjustably fixed to their respective shafts, so that they may be moved endwise thereon to accommodate different widths of en velop blanks.

@n shaft 197 between side frame 10 and creasing roll 194, is gumming roll 198 for applying gum to the edge of the bottom of l5 secondary feeding means, and the side flaps thereof folded by means of the turning' fingers already described, and then said bla-nk is delivered to the third advancing means comprising belts 81-and 82, ready to be again synchronized lengthwise of the machine and positioned crosswise thereof, previous to being creased for the end fiap fold- H13"- v v The means provided for positioning the side folded blank crosswise of lthe machine, comprises opposite blades 202 and 203 fixed to slides 204 and 205 respectively. Said slides are mounted for movement toward and from the path of the envelop blank in side frames 100 and 110 respectively, and are actuated inwardly by cam arms 206 and 207 respectively, fixed to` seal flap creaser shaft 208 and outwardly by springs 284 and 285 respectively. For retarding the partly folded blank lengthwise of the machine and into synchronism with the creasing mechanism, which is actuated at a speed slightly slower than that of feed belts 81 and 82, l provide stop 209 fixed to the periphery of creasing roll 210 fixed to shaft 211. Said stop 209 is adjustable circumferentially on roll 210 by means of the usual holding screws not shown, whereby the relation of the bottom flap creasing to the leading end of the bottom flap may be changed to accommodate different lengths of bottom flaps. For forming the seal flap transverse crease, I provide creasing blade 212 fixed to shaft 208 for coaction with roll 213 fixed to shaft 214. It will be observed that shafts 208 and 214 are mounted in carriage 97, adjustable lengthwise of the machine, whereby said seal flap creasing means may be adjusted toward and from the bottom flap creasing means on shafts 211 and 215, about to be described. Fixed to shaft 215 is bottom Hap creasing blade 216, for coaction with roll 210 on shaft 211 therebelow. Also carried by shaft 215 is gumming bar 217, for gumming that portion of the body of the envelop onto which the bottom flap is to be folded. Said gumming bar receives its gum from transfer bars 218 vand 219, carried in a frame on .shaft 220. 65 Said frame is adjustable crosswise of the creased for the bottom Hap and gum supplied to the body of the envelop for securing that flap, the blank is advanced with its upstanding bottom fiap into engagement with bar 224, whereby said bottom flap is turned over onto the gummed body of the blank, which thereupon passes onto roll 225 and under roll 226, whereby said flap is squeezed down onto the bottom of the envelop. Said nearly completed envelop then n passes under guide 227 and under roll 228,

and thence into the control of the fourth advancing lmeans comprising, against one face thereof belts 98 and 99, and against the other face thereof belt 111 and its companion belt. This fourth advancing means runs at a much slower speed than'that advancing means by which the envelops are delivered thereto, whereby the envelops are advanced by said fourth advancing means stacked or overlaid with overlapping seal flaps.

Between the fourth and fifth advancing means, I provide gum roll 229 for applying a continuous, film of gum to the overlapping -seal flaps. Said roll 229 is adjustable crosswise of the machine on its shaft 230, and receives its gum from roll 231 in gum box 232. The envelops in overlapping succession then advance into the control of the fifth advancing means comprising belts 119 and 121, and which belts are spaced apart a sufiicient distance to permit the gummed portion of the seal flaps to pass therebetween without contact with said belts. lfor drying the gum on the seal flaps the blanks are advanced at a slow speed by belts 119 and 121, and l preferably provide a blower 233 to supply a blast of air to said gummed flaps to facilitate the drying thereof. The completed envelops are eventually delivered by said belts 119 and 121 onto table 141, fixed to rod 142, approximately below the place at which the blanks are delivered into the machine.

For driving my improved machine, I fix to some one of the shafts as 234, pulley 235 to which power may be delivered from suitable source not shown, by the usual belt not shown. Said shaft has fixed thereto gear 236 driving gear 237 fixed t9 shaft 238 turning in a bearin in side frame 11; On the outboard end o said shaft 238 is fixed gear driving intermediate gear 240 turning freely on stud 241 fixed in side frame 11. Fixed to gear 240 and coaxially therewith is gear 242 driving on the one hand, gear Q45 fixed to shaft 87 and on the other hand, gear 2423 fixed to shaft 8B, and thence to gear Qll-l fixed to shaft GG.

For driving creaser roll shaft Q14, I fix thereto gear 246 connected by intermediate gear 24T with intermediate gear 2&8 fixed to shaft Q49, havinga bearing in side frame 1l. Also fixed to said shaft 249 is gear F250 slightly larger than gear Q48. and meshing with and driven from intermediate gear Q42. The difference in size between gears 248 and 250 is to cause creasing roll il?) and its interconnecting mechanism to travel at a surface speed'slightly less than that of feed belts as 8l. for purposes hereinbefore described. Gear 246 fixed to shaft 211i drives gear 231 fixed to shaft 208. Shafts 211 and 215 are geared together and through intermediate gears 253, 2:34v and Q55, are driven from gear 2418. Also gear 256 fixed to shaft 252 is driven from intermediate gear 253, and shaft Q57 carrying roll 228 has av gear fixed thereto, driven from gear 256 on shaft Shaft 220 has gear 259 fixed thereto driven from gear 2G() on shaft Q15.
